How do I keep 12v supply to chartplotter during power drop?

Thank you .
Do you know where would that supply module be on a F33?
The mfd is at the flybridge helm.

I would say the lower helm position, but I would not be surprised to find a unit at the upper station.

I will have a looka s have the upper helm access open due to recently fitted vhf - needing a stng backbone cable. I don't recall seeing the supply pack but I have not been looking for it .

It is only small 50 x 40 x 12 mm and black. probably by Volvo keys, to provide a feed from both batteries.
